Eric's cam challenge

I have NOT read 13 pages, but from a cursory look at his chart..... was it 15-20 hp difference from best to worst?
I can see a concern for a heads-up racer needing every hp he can get, but is 15hp worth this much work for a street/strip car?
Am I supposed to be unhappy when my 540 makes 685, instead of 700?

Agreed.

I only looked briefly myself. But I think that the biggest gap was between 1 and 2, and the gap between 2 and 15 was very small. This might suggest something as well.
